Question

Write the exponential function y = 400e^{-0.19t} in the form y = ab^t. (a) Once you have rewritten the formula, give b accurate to at least four decimal places. b = help (numbers) If t is measured in years, indicate whether the exponential function is growing or decaying and find the annual and continuous growth/decay rates. The rates you determine should be positive in both cases of growth or decay (by choosing decay the negative rate is implied). (b) The annual ? rate is % per year (round to the nearest 0.01%). (c) The continuous ? rate is % per year (round to the nearest 0.01%).
